Vitamin D Deficiency: Everything You Need to Know

Vitamin D deficiency has been a growing concern in the United States, with studies showing that a significant percentage of the population is either deficient or severely deficient in this essential nutrient. Although vitamin D promotes healthy bones and teeth, it’s also vital for well-being and many other functions.  Low vitamin D  levels have been associated with a range of health problems.  The importance of getting enough vitamin D cannot be overemphasized.  This blog post will explore the causes, symptoms, and treatment options for vitamin D deficiency. So, let’s dive into the world of the sunshine vitamin!

Vitamin D Synthesis: How Is Vitamin D Made

One of the unique aspects of vitamin D is that the body can synthesize it. When the skin is exposed to sunlight, a chemical reaction occurs, which helps the body produce vitamin D. The liver and kidneys then convert vitamin D into an active form, which the body can use. It is fascinating how our body can produce the vitamin D that it needs, highlighting the importance of spending time outdoors and getting enough exposure to sunlight.

Different Forms of  Vitamin D: D2 vs D3 Vitamin

vitamin-D2-D3

Vitamins are an essential component of a healthy diet, and two of the most important vitamins our body needs are D2 and D3. While both forms of vitamin D have numerous benefits, they differ in several ways. D2 is primarily found in plant-based foods and fortified foods, while D3 is produced naturally when our skin is exposed to sunlight and is found in animal sources. D2 and D3  play a crucial role in regulating calcium and phosphate levels in the body, which are required for strong bones, teeth, and muscles.  While both forms are essential, D3 is generally more effective than D2.   Our body uses  D2 by converting it into a more active form, D3.

Both vitamins improve immune function, regulate mood, and reduce inflammation. The recommended daily doses range from 400 to 800 IU, depending on age, gender, and other factors.  It’s essential to get a sufficient dose of either type.

Vitamin D  Benefits

Vitamin D has long been lauded for its effects on bone health, but did you know that this versatile vitamin also impacts other crucial areas of our bodies? Research has shown that adequate vitamin D levels can positively affect heart health, cancer prevention, and immune system function. Additionally, this vitamin plays a role in regulating the absorption of essential minerals like phosphorous. But perhaps most interestingly, low vitamin D levels have been linked to mood and cognition issues, indicating that maintaining adequate levels of this vitamin is crucial for proper brain function. So, go outside and soak up some sun (with sunscreen, of course) to reap the many benefits of vitamin D!

What Causes Vitamin D Deficiency?

Vitamin D is a fat-soluble vitamin that is produced in the body when we are exposed to sunlight. This is why it’s often called the “sunshine vitamin.”

 However, you may become deficient in this vitamin if you don’t get enough sun exposure. Other factors that can lead to a vitamin D deficiency include inadequate dietary intake of vitamin D-rich foods (such as oily fish and fortified milk), decreased vitamin D production due to liver and kidney diseases or conditions such as malabsorption syndromes associated with weight loss surgery,  and  GI  diseases which can impair the absorption of vitamin D.  Furthermore, certain drugs, such as prednisone and anticonvulsants used for treating epilepsy, can also interfere with our ability to absorb this vital nutrient. 

  Risk Factors for Low Vitamin D Risks 

Vitamin D is a vital nutrient that is important in maintaining our health. Unfortunately, low levels of vitamin D are all too common, especially among pregnant women, older people, and those with health conditions such as cystic fibrosis. Clinical trials have shown that maintaining adequate blood vitamin D levels can reduce the risk of complications associated with these conditions. 

There are several risk factors for low vitamin D, but the most common cause is a lack of sun exposure. The body produces Vitamin D when the skin is exposed to sunlight. However, many people spend most of their time indoors or live in areas with limited sunlight, which can result in a deficiency.

Those with dark skin, like those found in African Americans and other ethnic groups, are at a higher risk of vitamin D deficiency, as their skin is less able to absorb sunlight, which is one of the primary sources of vitamin D.  Other causes of low vitamin D include a poor diet lacking vitamin D or a condition interfering with vitamin absorption, such as Crohn’s disease, inflammatory bowel disease or celiac disease. Bariatric or gastric bypass surgery leads to decreased absorption of vitamins, especially vitamin D.

Vitamin D deficiency is a prevalent issue, particularly during winter months when sunlight is limited. Observational studies have linked low vitamin D status to a range of health concerns, including high blood pressure, risk of fractures, and colorectal cancer. Furthermore, vitamin D metabolism varies greatly among individuals, highlighting the importance of consulting a healthcare provider for personalized recommendations.  Individuals are less likely to suffer from vitamin D deficiency during the summer months. 

Breastfed infants and older adults are particularly vulnerable to vitamin D insufficiency, and infant formula and orange juice fortified with vitamin D can be helpful for those at risk. While randomized controlled trials have shown that vitamin D supplementation can lower parathyroid hormone levels, which are associated with adverse effects, the long-term effects of supplementation on cardiovascular health and overall cause mortality remain uncertain. Additionally, it is important to note that while the production of vitamin D can be stimulated by sunlight, excessive exposure can have harmful effects. Monitoring and maintaining optimal vitamin D levels is crucial for overall health and well-being.

Therefore, monitoring blood levels and ensuring sufficient vitamin D is obtained through diet or supplements, especially for those at a high risk of deficiency, is crucial.

10  Common Causes of Vitamin D Deficiency

causes-of-vitamin-d-deficiency

1. Not Getting Enough Sunlight

One of the primary causes of vitamin D deficiency is not getting enough sunlight. The body needs sunlight to produce vitamin D; without enough sun exposure, vitamin D levels can drop. People living in northern latitudes are at a higher risk for vitamin D deficiency as they may not get enough sunlight year-round. Additionally, people who spend most of their time indoors are at a higher risk as they are not exposed to as much sunlight. Patients hospitalized for long periods of time are more likely to suffer from vitamin D deficiency. 

2. Wearing Sunscreen

While protecting your skin from the sun’s harmful rays is important, doing so can also lead to vitamin D deficiency. This is because sunscreen blocks out ultraviolet (UV) light, which is necessary for the body to produce vitamin D. If you are going to be spending time in the sun, it is essential to choose a sunscreen that has a low SPF so that you can still get some exposure to UV light.

3. Having Darker Skin

People with darker skin are at a higher risk for vitamin D deficiency as their skin contains more melanin, which blocks UV light from reaching the underlying layers of skin. As a result, people with darker skin may need to spend more time in the sun to produce enough vitamin D.

4. Prescription drugs

Prescription drugs are known to have various side effects, and vitamin D deficiency is one of them. Many of the prescription drugs that people regularly consume can cause crippling deficiencies in this essential vitamin. Some of the prominent drugs responsible for such deficiencies include antacids, steroids, weight-loss drugs, anti-seizure medications, and even cholesterol-lowering drugs. However, not everyone taking these medications will experience a deficiency. The extent of the deficiency is dependent on various factors such as age, diet, and level of sun exposure. Nonetheless, it is essential to be aware of how prescription drugs can impact your health and consider consulting a healthcare provider to manage any potential deficiencies.

5. Age

As people age, their bodies become less efficient at producing vitamin D. Additionally, older adults are more likely to spend time indoors and are less likely to get outside for prolonged periods. As a result, older adults are at a higher risk for vitamin D deficiency.

6. Obesity

Obesity is another major risk factor for vitamin D deficiency, as fat cells can absorb and store vitamin D, making it unavailable for use by the body. This is why people who are obese often have lower levels of vitamin D, even if they are getting plenty of sunlight exposure.

7. Kidney Disease

Kidney disease can also lead to vitamin D deficiency as the kidneys convert vitamin D into its active form. If the kidneys are not functioning properly, they cannot convert enough vitamin D into its active form, leading to a deficiency.

8. Liver Disease

Like kidney disease, liver disease can also lead to vitamin D deficiency, as the liver converts vitamin D into its active form. If the liver is not functioning correctly, it cannot convert enough vitamin D into its active form, leading to a deficiency.

9. Crohn’s Disease

Crohn’s disease, irritable bowel, and Leaky Gut are inflammatory bowel diseases that can lead to malabsorption issues, meaning that the body cannot absorb nutrients from food properly. This includes vitamins and minerals like vitamin D, which can lead to a deficiency if not enough is absorbed from food sources.

10. Stress 

Stress has become an increasingly common aspect of modern life. Whether it’s due to work, family, or social pressures, stress can have a serious impact on our physical and mental health. One of the ways in which chronic stress can harm our bodies is by depleting our levels of vitamin D. But how exactly does stress decrease vitamin D? Recent studies have suggested that stress may interfere with the absorption and metabolism of vitamin D, as well as reduce the amount of time we spend outdoors in the sunlight (which is the primary natural source of vitamin D). By understanding this connection between stress and vitamin D, we can take steps to mitigate the harmful effects of stress on our bodies and improve our overall health and well-being. Given the important role that vitamin D plays in our overall health, it’s essential to take steps to manage our stress levels to avoid any potential deficiencies. Adding some relaxation techniques to your daily routine might be the key to keeping your vitamin D levels in check.

How To Test For Vitamin D Deficiency

Testing for Vitamin D Deficiency:

If you suspect that you may be deficient in vitamin D, there are several tests that your doctor can perform to confirm your suspicions. The most common test is a blood test, which measures the vitamin D level in your blood. 

A simple blood test for vitamin D can provide you with this information. With a quick and painless blood test, you can find out if you need to increase your vitamin D intake or if you’re getting enough from your diet and sun exposure. Knowing your vitamin D status can be a small but powerful step in taking control of your health.

 The usual test range of vitamin D levels ranges from 40 to 100 nanograms per milliliter.  Inadequate vitamin D levels are anything below 40 is considered a low vitamin D level.  Adequate levels of vitamin D  levels should be above 60 or higher for optimal health.

Increasing Vitamin D Levels 

  Your holistic doctor may recommend vitamin D injections and supplements if your levels are low. Vitamin D supplements come in several forms, including pills and drops.  It’s essential to discuss the best option for you with your doctor before starting vitamin D supplementation.

The Institute of Medicine recommends a daily intake of 600-800 International Units (IU) of vitamin D to maintain normal vitamin D levels. Recent studies have demonstrated the effectiveness of vitamin D supplementation in improving vitamin D status. Higher daily doses of vitamin D doses of supplements containing 10 to 20,000 iU may be necessary for some individuals who have a severe vitamin D deficiency, trouble making vitamin D, absorbing it, and whose bodies quickly burn through vitamin D.

If vitamin D injections are needed to dose ranges from 50 to 100,000 IUs per injection on a weekly or monthly basis, depending on the severity of the vitamin D deficiency,  

In addition to injections and supplements, several ways to increase your vitamin D levels naturally exist. The most obvious is spending time in the sun. Aim for 15-20 minutes of sun exposure a day, without sunscreen, if possible. Ensure you get out of the house, especially during the summer months.  Eat foods high in vitamin D, including fatty fish, egg yolks, and fortified dairy products. If you have a condition that interferes with vitamin absorption, it’s crucial to speak to your doctor about the best ways to manage your vitamin D levels. While it’s essential to get enough of this nutrient, it’s also possible to consume too much vitamin D. For this reason; vitamin D supplementation should be done carefully and under the guidance of a healthcare professional. 

Conclusion:

In conclusion, vitamin D deficiency is a more common problem than you might think. It’s essential to be aware of the symptoms and causes to take steps to ensure you’re getting enough of this crucial vitamin. There are many benefits of vitamin D, therefore it is important to make sure that you are getting enough vitamin D each day. If you suspect you are deficient, speak to your health care provider.
